## Requirements

- Python 3.8+
- python-dotenv >= 1.0.0
- PyYAML >= 6.0
- cryptography >= 41.0.0
- click >= 8.0.0

## Configuration

### Environment Variables
```bash
ENV_MANAGER_KEY=your-master-encryption-key
ENV_MANAGER_ENV=development
```

## Usage

### Load and Switch Environments

```python
from env_config_manager import EnvManager

# Load .env file
env = EnvManager.load(".env")

# Switch to production config
env.switch("production")

# Get variable with fallback
db_url = env.get("DATABASE_URL", default="sqlite:///default.db")
```

### Encrypt Secrets

```python
from env_config_manager import SecretVault

vault = SecretVault(key="your-master-key")
encrypted = vault.encrypt("super-secret-api-key")
# Store encrypted in .env: API_KEY=ENC(vault,encrypted_value)

decrypted = vault.decrypt(encrypted)
```

### Validate Configuration

```python
from env_config_manager import ConfigValidator

schema = {
    "DATABASE_URL": {"required": True, "type": "url"},
    "PORT": {"required": True, "type": "int", "min": 1024, "max": 65535},
    "DEBUG": {"required": False, "type": "bool", "default": False}
}

validator = ConfigValidator(schema)
errors = validator.validate(env)
```
